This is the first detection of Hawking radiation. Hawking radiation is usually associated with the slow evaporation of black holes, as photons emitted from the event horizon. But the observable universe also has a horizon. Hawking radiation should be coming from this horizon, and also from every horizon in the universe — in other words, from every point in the universe, says cosmologist Max Tegmark (MIT). Today the cosmic horizons are huge and their Hawking radiation is utterly insignificant. But in the universe’s first fraction of a second, the horizons were tiny and sharply curved. The gravitational waves announced today are these horizons' Hawking radiation.
What do you think about this? Is it really first evidence of Hawking radiation?

Yes I agree that universe was tiny just after big bang. Then inflation
took place when universe expanded. Please explain what is the
connection to Hawking radiation and gravity waves in this picture.
I have just seen a video in the website of Nature. The video is
entitled "The beginning of everything". Link is,

The video says that a group of American scientists
have conducted an experiment at Antarctica for nine
long years. They have found signatures of gravitational
waves imprinted within CMBR. These waves were
generated during inflation when space was expanding
with a speed which is much faster than speed of light.
